| The journal impact factor is a measure of the frequency with which the "average article" in a journal has been cited in a particular year. The impact factor will help you evaluate a journal's relative importance, especially when you compare it to others in the same field.
The impact factor is calculated by dividing the number of current citations to articles published in the two previous years by the total number of articles published in the two previous years. Example: Cites in 2003 to articles published in: 2002= 9850 2001 = 12648 2001 + 2002 = 22498 Number of articles published in: 2002 = 379 2001 = 406 2001 + 2002 = 785 Calculation: (Cites to recent articles 22498 ) / (Number of recent articles 785 ) = 28.660 附件是2003年SCI影响因子简表，仅供参考。 附:简表,按影响因子排序 附:简表,按期刊名排序 |
